A
flood relief channel built at the cost of £83.5
million to shift the seasonal
flooding from one side of the Thames to the other. It removed the
old settling beds at Slough Sewage farm and has left 250000 trees
and gravely islands knee-deep in vegetation! Considered by
some as an opportunity missed. Still, it has produced some good passage
birds and is a pleasant hour or so walk if you get there before the dogs.
